New brake m/c fitting help.

[moanthebairns]

Went to fit my new hel m/c to the road daytona and after stripping the standard off it clicked, eh there's no brake light switch.

Has anyone used a light switch of a banjo bolt? Does it work.

Next question, the m/c inlet from the reservoir looks about 8mm dia (I haven't measured it as I can't find my calipers) the reservoir outlet looks about 10mm dia is there a way to solve this discrepancy. I had it with my track bike and had to buy a brembo reservoir. I have a fancy metal triumph one that I sorta like and would want to keep.

Obviously a 10mm hose would fit both and I could use a more secure clamp at the m/c but this slightly concerns me for it weeping.

A 8mm dia hose probably wouldn't work on the res outlet.

Regarding the banjo bolt switch, I had success with one of these. I had a Panigale R with Brembo RCS master cylinders and the clutch one did not have any facility to mount the clutch switch. With the Panigale, when you pull the clutch in (and activate the switch) it switches the ECU to an idle map, and so without said switch this bike wouldn't idle and kept cutting out. Moto Rapido pointed me to the solution straight away (i.e has it got aftermarket levers and master cylinders) So in answer to (part of) your question, there is no reason why a banjo switch won't solve the issue

An 8mm pipe can be heated to allow it to stretch over the bigger port, easier than trying to incorporate a reducer into the short line.

As for the lack of light switch, you'll probably need a pressure switch but it's a less than ideal solution on many fronts.

Is there no way to attach a micro switch underneath the M/C housing??

However, cheap enough so it seems..

I've had a banjo bolt switch for 4 years on my srad with no problems, think mine is a HEL switch intact.

Also have a HEL m/c on the track bike, mine came with their reservoir and tube so worth asking them if yours is missing? I did have to buy a little bracket to mount their reservoir as the mounting hole is at a weird angle.

I've got a banjo/pressure switch on my 916 front master cylinder, it works but doesn't activate until a reasonable pressure is applied so if braking only lightly (e.g. just gentle riding in slow traffic) doesn't always light the brake light.

I've also got them on both my Monster and Guzzi rear brakes where they work fine but I think that's down to the fact that the rear bakes need more pressure due to the caliper setup and so activate every time the brake is used.

Interesting - what MC did your Daytona have on it and why are you replacing it for a HEL? I now have an ex-Daytona Nissin 19mm radial MC on my ZX9R and am waiting for the forks to come back before I bolt up the (new) HEL lines and fill/bleed it.

So I finally got some parts to complete this. I called Hel and the chap apologised about it not having a brake light switch on it. His words were 'I wish management would really allow the time for design before rushing through something that's not ready'. Reassuring purchasing a brake lever.

He is sending me out a reservoir free but never had brake lines, so gave me a supplier's number. I purchased the banjo pressure switch (its the one brembo use, so naturally it was twice as much as anything else on the market at £25) and brembo hose. I thought it best not to search ebay and amazon for brake parts to save a tenner.

I fitted some 6mm i/d hose, it fitted over the larger diameter reservoir. However the smaller hose clips I got didn't expand enough to get it onto the reservoir outlet and the bigger clips for the oem hose wouldn't clamp. So I had to bodge it with some black insulation tape, hopefully the glue in the tape doesn't perish the hose.



I also discovered that the brake mount is wider that the original lever. This presents a problem on standard clip ons. The ignition switch unit has an internal locating pin that goes into the bar. Moving it along to allow the brake lever on means you miss that hole. It's clamped up but there is a slight gap on the unit. This should only be a cosmetic problem as with my track bike I had the same issue due to aftermarket clip ons, naturally they never had a hole on the bar to allow for this switch.



I had to feed the throttle cable from the top, Its not an ideal run (originally bottom fed) but it doesn't alter the throttle lock to lock, so should be fine..

I bled the whole system but couldn't get any feel on the lever. I then noticed at the banjo it's leaking slightly. I made the mistake of reusing copper washers again I think.

So, drain it all again, fit new washers, bleed again (who the fk thought it was a good idea to put bleed nippels on the inside of a caliper I'll never know) and it seems fine.

whilst I broke lockdown rules riding it 50 yards to hose it down worried incase I dribbled brake fluid anywhere, sadly I never got much useable feedback at four miles an hour.

I kinda wish I'd just got another brembo with all the fking about. They're a doddle to fit on road and track bikes. I have a brembo on my ninja, I might swap it over so everything looks as it should. I dunno. We will see how it performs. I do plan on getting the hel calipers replacing the six pots so be nice to have it all matching....

Sounds like a right palava! I'd only use those house clamps as a temporary measure as the electrical tape will go manky in the end.
